Refactor Settings and Task Views for API Base URL Management

- Deprecated `ApiSettingsViewModel` in favor of enhancing `SettingsViewModel`.
- Moved the API Base URL field from `TaskView` to `SettingsView` to centralize configuration.
- Integrated `RestApiUtility` dependency into `SettingsViewModel` to ensure consistent URL management across the app.
